12 Claims.

This invention relates to an article of furniture and in particular to a table model lamp with a complete radio receiver including a chassis incorporated in the pedestal and an antenna therefor in the lamp shade. p

I One of the objections to building radio receiving sets in lamps and the like is the awkward appearance resulting from the combination; therefore, the primary object of this invention is to make the combination in such a manner that the general and outward appearance of the lamp is not altered and which from all outward appearances will have the same appearance as a corresponding lamp without a radio set therein, the radio set elements being completely concealed. It is contemplated to supply these lamps ,in pairs, particularly for use in boudoirs, or on pianos, mantelpieces, and the like, with the radio -.set incorporated in only one of the lamps.

In incorporating radios in articles of furniture,

:and even in automobiles and other devices, the .radio receiver chassis is substantially inacceszsible; therefore, this invention involves a lamp ;having a pedestal with a removable cover in which zthe light bulbs of the lamp, antenna, and the com- ;plete radio receiver chassis, are mounted upon the said cover and removable therewith.

A further objection to combining radio recceiving sets, particularly in lamps, is that it has been found advantageous to mount the antenna loop in a vertical position and turn the carrier 'or signal to such a position that the antenna will mover the angular incidence of incoming radio waves and this necessitates turning the lamp, sometimes to awkward positions; whereas the antenna loop in the lamp of this combination is rotatably mounted within the shade so that it may be rotated independent of the shade to substantially any position without moving the shade or lamp.

The combination of a radio set with articles of furniture is also objectionable because space must be provided for the observance of the tuning dial and, therefore, this invention contemplates the use of a translucent plate, preferably with decorative designs thereon, forming a face of the lamp, and a projection system whereby the numerals on the tuning dial are projected on the plate so that they may readily be observed from the exterior of the lamp.

In combining a radio set with an article of furniture, it is also necessary toprovide space for the knobs of the tuning condenser and volume control, and, as projecting knobs are objection- ..able, the knobs of the radio set of thisvinvention are incorporated in the cover of the pedestal and positioned in the upper surface thereof where they are concealed by the lamp shade.

In designing articles of furniture to include the complete elements of a radio set, it is also necessary to provide an open area covered by a screen to form a grille, and this usually results in an unsightly surface, so that in the pedestal of the lamp of this invention decorative grilles are provided at the four corners to provide a balanced cabinet, even though only the two grilles at the forward corners may be used.

Attempts to incorporate radio apparatus in table lamps with very little change or alteration in the design and construction of the lamp have been made but in doing so the units of the radio set have been separated and positioned at various points thereby complicating wiring, and particularly repairing; for this reason the pedestal of the lamp of this invention is formed with the complete radio receiver chassis incorporated therein and readily removable therefrom, as a unit.

Radio cabinets are commonly formed with the baflle surrounding the speaker stationary in the cabinet and when the radio receiver chassis is removed for repair and replaced, it is necessary to reposition the chassis so that the periphery of the speaker will register with the bafiie, which is a relatively difficult operation; To overcome this, the baffle around the speaker of this invention is mounted on the chassis so that it is removable therewith and is, therefore, always registering with the speaker.

The purpose of this invention is to provide a lamp radio receiving set having a complete, compact chassis incorporated in the pedestal of a lamp and-with the antenna rotatable in the shade thereof without detracting from the general appearance and design of the lamp.

In addition to the location and position of the antenna loop, the invention involves a new and novel loop design in which the fine wires of the loop are wound on a transparent plastic, which eliminates the possibility of shadow being cast upon the lamp shade or downward, as hereinafter more fully described. The loop being formed of a frame of transparent plastic within the confines of the lamp shade and capable of being rotated substantially through a complete circle overcomes the disadvantages of the stationary antenna and at the same time makes it possible to use a cluster of light bulbs, thereby meeting requirements of the average user.

With the loop mounted in this manner, the con- The difiusion of the light around the small wires in turn is determined by such factors as the distance of the light source from the wires; also the intensity of the light source, as well as the distance of any panel or wall, as for example the lamp shade l2, which would receive a shadow; thelatter being away from the wires gives more space for the diffused light to obviate any shadows.

The upper end of the loop or frame I4 is pivotally mounted in the upper part of the shade onthe lamp stem 29 at the point 39 and by turning the sleeve Hi the antenna may be rotated around the stem independent of the shade and light bulbs. The sleeve !5 provides a cover and therefore protection for the leads of the antenna, and also supporting and controlling or adjusting means for the antenna.

'The stem 29 extends downward through an opening 3| in the sleeve and through an opening 32 in the cover [9 providing supporting means forv the lamp, shade and antenna, and also providing a passage for wires 33 and 34, which supply current to the light bulbs above and to the radio receiver below, and extend downward through the pedestal and through a nipple 35 at the lower end. The stem 29 is locked in the cover byv a lock nut 36 threaded on the lower end thereof as shown in Figure 2. The nipple 35 is mounted, inan extending flange 31 of the chassis frame.

stem 29 through a socket with extensions 46, and the lamp shade I2 is held stationary at the upper end of the stem by the usual ornamental nut 41.

-The lower end of through an opening 48 in a flange 49 at the upper end of the chassis frame l3 and by this means the frame [3 is also held stationary in a recess in the lower surface of the cover ID. The flange 49 is also provided with openings 59 and 5! for the stems of the operating knobs.

The design and construction of the radio receiver chassis, which comprises the usual tubes, condensers, transformers and the like, all of which are standard articles of manufacture, is not described in detail. The relative positions of these parts, however, as illustrated in Figures 2 and 4, .is described as with the antenna coil 21, the first I. F. transformer 52, converter tube 53, I. F. tube 54 and oscillator coil 55 positioned above the tuning condenser 56; and with the second I. F. transformer 51 and second detector tube 58 positioned below and directly associated with the tuning condenser, and the power output tube 58 and. the rectifier tube 60 positioned at the lower end of the chassis, better results are obtained. The loud speaker 6| with its baffle 62 is also positioned adjacent the lower end of the chassis and is mountedso that the face thereof is perpendicular to the surface of a table or stand upon which the lamp may be placed'so that the acoustic angle into which the loud speaker diaphragm radiates is reduced to 90 whereby the low frequency air loading is improved and this in turn increases the low frequency generally lacking in all small receivers.

the stem 29 also extends o The tuning condenser is provided with a drufii 63' having calibrations 64 thereon and these are projected through a lens system 65. by a light source 66 to a translucent plate 61, forming the face of the cabinet as illustrated at 6B in Figure 1. Theplate 61 may have designs as indicated by the numeral 69 thereon and similar plates may be used at the back and sides. It will also be understood that the numerals representing the calibrations of the tuning condenser may be projected to the face of the cabinet or to any point by any other means or in any manner.

The tuning condenser 56, in the design shown, is rotated by a knob 10 substantially hidden in a recess H in the cover In below the shade I2 and this knob is mounted on a shaft 12 extending downward through an opening 13 and provided with a pulley 14 at the lower end, which through a cable I5 rotates the tuning condenser, passing around a pulley 16 on the condenser and over idlers H and 18. The cable 15 may be provided with a spring 19 or other means for taking up slack therein. It will be understood that the knob of the tuning condenser may be located at any other point and may be connected to the con denser by any means. The device is also provided with a volume control knob 89 on a shaft 8! extending downward through an opening 82 and this turns a switch 83 and operates the usual volume control. This knob is also located in the recess H and substantially hidden/by the cover [0 and lamp shade l2.

The pedestal I l is formed with front and back walls 84 and 85 (see Figure 3), and end walls 86 and 81, and in the design shown the front and back walls are covered with removable plates 61 and 88, the plate 61 at the front covering an opening 89 through which. the calibrations of the tuning condenser drum are projected, and these plates are slidable in grooves 90 at the edges. Similar plates 9| and 92 are also slidably held in grooves 93 at the ends.

The corners of the cabinet are shaped as shown in Figure 3 and the surfaces thereof are provided with openings 94, 95, 96 and 91, and these surfaces and openings are covered with grilles 98, 99, I90 and NH respectively. These grilles are also slidably mounted in grooves I02 at the edges as shown.

The construction of the lamp radio receiving.

set will be understood from the foregoing description. In use the parts may be assembled as described and shown, particularly in Figure 1,

.and as stated before the lamps may be provided in pairs, one with and one without a radio set incorporated therein, and from general appearances it will be impossible to tell whether a lamp is provided with a radio or not. The lamp bulbs may be used independent of the radio set and either or both may be turned on or off as desired. In using the radio, it is only necessary to turn the knob 80 and then adjust the knob 10 until a station is tuned in, and these may be operated by the thumb and forefinger of a hand that may be placed upward under the shade.

The antenna may readily be positioned for the best reception by turning it to substantially any angle withoutmoving the lamp or shade.

-The light bulbs may readily be changed or replaced without interfering with the operation of the radio set, and the. tubes or other parts of the receiver may be changed or replaced by removing the entire chassis from the pedestal or cabinet and, as the chassis is permanently attached to the cover, it is only necessary to release While a preferred specifi'c'e'mbodiment ofthe" invention is herei'ribe'fore set forth, it is to be clearly understood that, the invention is not to be limited to the exact." construction" illustrated and described because variousmodifications' or these details maybe" provided in putting" the" inventiorifinto practice within the purview of" the appended. claims;
